A motorcyclist moving at an estimated 120 MPH smashed headlong into the rear of a semi rig early Tuesday morning.
Tuesday afternoon, Tulsa police identified him as Brandon White, 25, of Tulsa.

It happened shortly after 1:00 a.m. near the 8100 block of South U.S. 169.

The motorcycle traveled several hundred yards after impact, ending up about 8500 S. U.S. 169. The truck was nearly to 91st Street before it could come to a complete stop.

Emergency responders say White died instantly, despite the fact he wore a helmet.

He actually impaled himself into the rear of the truck, head first, and was then dragged along behind the truck until the driver of the semi could pull it over.

Rescue workers found him dangling from the rear of the truck.

The trucker told officers the impact made him think he'd been hit by another truck.

The medical examiner will try to determine if White might have been intoxicated at the time.

Accident investigators believe his speed at time of impact was around 120 MPH.
